Viruses use the host cell machinery to replicate. However, some viruses replicate their genomes by a mechanism that host cell cannot support. How can these types of viruses infect and replicate in their host, when the host cell cannot perform a particular role that the virus requires?a) The viral genome encodes the specialized enzymes that the host does not have.b) The virus causes mutations in the human cells, resulting in the formation of new enzymes that are capable of performing these roles.c) The virus infects only those cells and species that can perform all the necessary replication roles.d) Viruses can stay in a quiescent state until the host cell evolves this ability. e) All of the above have been frequently observed.
a) The viral genome encodes the specialized enzymes that the host does not have.
Viruses replicate with the aid of inserting their genetic code into the gene pool of the host mobilephone, this replicating together with the phone because the telephone goes by means of its cycles. Finally, the virus destroys the host mobile so it may well move to other cells where it may well infect and replicate in greater numbers.
